Local Government means any county, city, or town having its own government for local affairs. Mine Dewatering Water means any water that is impounded or that collects in the mine and is pumped, drained, or otherwise removed from the mine through the efforts of the mine operator. This term shall also include wet pit overflows caused solely by direct rainfall and ground water seepage. However, if a mine is used for treatment of process generated waste water, discharges of commingled water from the mine shall be deemed discharges of process generated water. Municipality means a political unit such as a city, town, or county, incorporated for local self-government. National Pollutant Discharge Elimination System (NPDES)means the national program for issuing,modifying,revoking, and reissuing, terminating, monitoring, and enforcing permits, and imposing and enforcing pretreatment requirements,under sections 307,402, 318, and 405 of the Federal Clean Water Act, for the discharge of pollutants to surface waters of the State from point sources. These permits are referred to as NPDES permits and,in Washington State, are administered by the Washington Department of Ecology. Sand and Gravel General Permit Fnal.doc June 25, 1999 � t x Page 49 of 51 that just one sampling point is required. However,if some puddles are from a gravel stockpile area and others are receiving water from a concrete batch area,two sample points are likely. It may be helpful to test multiple puddles for pH. Those with essentially the same pH value can probably be represented by one sample. Surface Water Discharges: Discharges of process water should be timed to occur when the facility is running at full capacity. Discharges of stormwater may be taken at any time a stormwater discharge occurs. For all parameters required by this permit, a grab sample of instantaneous measurement will be considered representative. The intensity of a storm event and the number of dry days preceding a storm can have dramatic effects on the characteristics of a stormwater discharge. Frequency of sampling must be sufficiently frequent to represent this variability. Since weather can not be readily predicted far in advance, sampling on short notice is likely. Sanitary Sewer means a sewer designed to convey domestic wastewater. Sediment means the fragmented material that originates from the weathering and erosion of rocks or unconsolidated deposits and is transported by, suspended in, or deposited by water. SEPA (State Environmental Policy Act) means the Washington State Law, RCW 43.21C.020,intended to prevent or eliminate damage to the environment. Significant Amounts means those amounts of pollutants that are amenable to treatment or prevention or that have the potential to cause or contribute to a violation of standards for surface or ground water quality or sediment management. Significant Materials includes,but is not limited to: raw materials; fuels; materials such as solvents and detergents;hazardous substances designated under section 101(14)of CERCLA; any chemical the facility is required to report pursuant to section 313 of title III of SARA; fertilizers;pesticides; and waste products such as ashes, slag, and sludge that have the potential to be released with stormwater or process water discharges. Silvicultural Point Sources are timber tract and logging activities (SIC codes 0811 and 2411)that produce mined materials for use in forest management. Additionally, silvicultural point source activities are limited to rock crushing or gravel washing operations that use a discernible, confined and discrete conveyance to discharge pollutants to surface waters of the state. Site means the land or water area where any "facility or activity" is physically located or conducted. Source Control BMPs means physical, structural, or mechanical devices.or facilities intended to prevent pollutants from entering stormwater. A few examples of source control BMPs are erosion control practices, maintenance of stormwater facilities, construction of roofs over storage and working areas, and direction of wash water and similar discharges to the sanitary sewer or a dead end sump. sand and Gravel General Permit Final.doc June 25, 1999 w � Page 51 of 51 Type 1 Stormwater means stormwater from portions of a site where no industrial activities have occurred or from a site or area within a site that has been reclaimed and the reclamation bond portion thereof(if any) has been released. If type 1 stormwater enters areas associated with type 2 stormwater, it becomes type 2 stormwater. Likewise,if it enters areas associated with type 3 stormwater, it becomes type 3 stormwater. Type 2 Stormwater means stormwater from: 1)portions of a site where mining has temporarily or permanently ceased; 2) storage areas for stockpiles of raw materials or finished products; 3) or, from portions of a site with exposed soils in areas cleared in preparation for mining or other industrial activity. If type 2 stormwater enters areas associated with type 3 stormwater, it becomes type 3 stormwater. Type 3 Stormwater means stormwater discharges from 1)industrial plant yards; 2) immediate access roads and rail lines used or traveled by carriers of raw materials, manufactured products,waste material, or by-products used or created by the facility; 3) material handling sites;4) sites used for the storage and maintenance of material handling equipment; 5) sites used for residual treatment, storage, or disposal; 6) shipping and receiving areas;7) storage areas for raw materials or intermediate and finished products at active sites; 8) and, areas where industrial activity has taken place in the past and significant materials remain and are exposed to stormwater. USEPA means the United States Environmental Protection Agency. Water Quality means the chemical, physical, and biological characteristics of water, normally with respect to its suitability for a particular purpose. Waters of the State includes those waters as defined as "waters of the United States" in 40 CFR Subpart 122.2 within the geographic boundaries of Washington State and "waters of the state" as defined in Chapter 90.48 RCW. This includes ground water, lakes,rivers, ponds, streams,wetlands,inland waters, salt waters and all other surface waters and water courses within the jurisdiction of the State of Washington. Wellhead Protection Area (WHPA).means the portion of a well's, well field's, or spring's zone of contribution defined as such using WHPA criteria established by the Washington Department of Health. Sand and Gravel General Permit Final.doc June 25, 1999 FACT SHEET SAND AND GRAVEL GENERAL PERMIT On July 6, 1994, the Department of Ecology(Ecology) issued the Sand and Gravel General Permit. That permit expires on August 6, 1999. A proposed general permit has been prepared to replace the expiring general permit. This fact sheet is a companion document to the revised National Pollutant Discharge Elimination System(NPDES) and State Waste Discharge sand and gravel general permit. The proposed permit provides coverage for discharges of process water, stormwater, and mine dewatering water associated with sand and gravel operations, rock quarries, and similar mining operations, including stockpiles of mined materials. It also provides coverage for concrete batch operations and hot mix asphalt operations. Operations covered under this permit are authorized to discharge wastewater to waters of the State of Washington subject to the conditions contained in the proposed permit. This fact sheet explains the nature of the discharges,Ecology's decisions on limiting the pollutants in the wastewater, and the regulatory and technical bases for those decisions. Public involvement information is contained in Appendix A. An advisory group participated in the development of the proposed permit and Appendix C includes the mission and members of this group. The proposed general permit provides protection of ground water, surface water, and sediment in waters of the state by limiting the discharge of pollutants in process water,mine dewatering water, and stormwater. The pollutants that are limited in this proposed general permit result from the processing of mined material, the manufacture of concrete and asphalt, stormwater runoff,mine dewatering, and from equipment and materials associated with this industry group. Chemical or physical treatment of the wastewater may be necessary to comply with the conditions and limits in this permit. All sites must implement Best Management Practices (BMPs) to control stormwater and minimize soil erosion on site. Stormwater may also require treatment before discharge to waters of the state. This proposed general permit limits the discharge of pollutants to surface waters under the authority of the Federal Water Pollution Control Act (U.S.C.S. 1251) and limits the discharge of pollutants to surface and ground water under the authority of Chapter 90.48 RCW.

Some facilities may require coverage for stormwater only. Coverage for timber tracts and logging activities (SIC codes 0811 and 2411) only includes those mining activities associated with the forestry industry that classify as silvicultural point source. Silvicultural point source activities are limited to rock crushing or gravel washing operations that use a discernible, confined and discrete conveyance (e.g. ditch, pipe) to discharge pollutants to surface waters of the state. The United States Environmental Protection Agency (EPA) pursuant to a court order, excluded most forest management activities from NPDES permit coverage. Additionally,best management practices for gravel pit sites are set by forest practice regulations under the Forest Practices Act, RCW 76.09. However, this exclusion only applies to activities that produce materials for use in forest practices. Any commercial mining operation operating on forestland is subject to the same coverage requirements as any other commercial mining operation. The criteria for coverage under the proposed general permit are listed in Special Condition S1, Permit Coverage. All facilities identified by the SIC Codes listed above and which meet the criteria of Special Condition S 1 must apply for and be covered by the proposed general permit, even if the only discharge is stormwater. In addition to these activities,related activities(e.g. SIC 3272 - Concrete Products, Except Concrete Blocks and Brick) may be considered for coverage under this general permit. Coverage may be offered when Ecology determines that discharge characteristics are similar and the permit conditions satisfy applicable state and federal requirements. Since a general permit is designed to provide environmental protection under conditions typical for the covered industry group, it will not be appropriate for every situation. Environmental protection can not always be assured when site specific conditions at a facility are not typical of the industry group or are beyond the scope of the proposed general permit. Special Condition S1.D. identifies specific situations where facilities are excluded from coverage under the proposed general permit and may require coverage under an individual permit. Special Condition S2, Coverage Requirements,describes how to obtain coverage as authorized under WAC 173-226-200. Public notice requirements, SEPA compliance and effective date of coverage are also covered under S2. There are some differences in application requirements for new facilities versus existing facilities. Special Condition S2 defines new and existing facilities and coverage requirements. In addition to typical site coverage, S2 provides for coverage of portable facilities. Under the current permit, portable operations(rock crushing, concrete batch, asphalt batch) could only Page 2 r FACT SHEET and biological activity that often will remove pollutants before they-can enter ground water. Therefore mining activities which remove vegetation and topsoil will typically make underlying ground water more vulnerable to pollution. MINE PROCESS WATER Some use of water is necessary at most mining-related facilities. In mining operations, water may be used in the mining,processing, handling, or transporting of the mined material. This water is categorized as process water. Most process water results from dust control or washing and screening mined rock products. Water may also be used to clean truck tires and wheels and prevent tracking of mud and dirt onto public paved roads. In addition to these easily identified sources of wastewater, many other activities at a mining facility can impact ground water and surface water quality and will be considered in this proposed general permit. These activities include wastewater from concrete truck cleanup, asphalt truck release agent application, equipment maintenance, and spills or leaks from tanks and equipment. Facilities at which many activities take place, from mining through batch plant operations, generate the greatest volume of wastewater and have the most varied sources of potential water contamination. Rock crushers are often used in the mining process to provide material that meets job specifications..Processing the material may also include washing. While rock crushers are often a permanent component of a site, there are portable facilities that move from location to location. There is often very little lead-time before these portables must begin operation at a site and they are typically only at,the site for a short period. The short notice and transient nature of these facilities create different permitting considerations for these facilities but they must still be able to assure compliance with permit conditions. Whether permanent or portable,rock crushers may generate process water and require best management practices for stormwater management. MINE DEWATERING WATER Mine dewatering water is a type of wastewater generated at some mining facilities which is not a direct result of using water to accomplish a processing function. This water is incidental to the mining operation and includes water that seeps into the mine or accumulates due to precipitation into the mine. Suspended solids may be the only contaminant requiring treatment in these circumstances. Water entering the mine site and subsequently becoming commingled with process water becomes process water and is subject to process water requirements. CONCRETE BATCH PLANTS Concrete batch plant operations (both permanent and portable) are commonly associated with sand and gravel mining. There are currently about 150 permits under the sand and gravel general peanut that include concrete batch operations. An operator typically controls the batching or mixing process from a central control room. Solid components are metered by weight while water and chemical admixtures are metered by volume. Dry materials may be added to a truck from overhead silos and mixed with water in the truck or they may be premixed at the facility and transferred to the truck wet. Truck capacities typically range from 5-12 cubic meters. Page 4 FACT SHEET is no discharge of process water from these systems. Typically the collected dust (fines)is reused in the manufacture of asphalt. The other type of system, wet scrubbers, uses water to capture the dust. Water sprays remove the air pollutants but transfer them to the resulting wastewater. The amount of water needed in a wet collection system may range from 50 to 200 gallons per minute. The wastewater must be discharged to a lined pond or holding tank. The water from the pondltank is typically reused in the scrubber after settling the particulate matter. Even after treatment, this process water cannot be discharged to surface water but may be infiltrated to ground. The settled particulate matter may be returned to the asphalt manufacturing process. When the fines from a baghouse or wet scrubber are not reused or cannot be completely reused, disposal becomes an issue. Land application of this material may be acceptable but testing should be conducted to determine if more restrictive disposal options are required. Except for cleaning within maintenance shop areas, delivery trucks are not typically washed on site but do receive a release agent applied to the bed of the truck before loading with asphalt. An application area is provided with a raised platform and spray nozzles. There are many release agents available but most of those currently in use are not petroleum based. Traditionally diesel was used and it is still in use at some facilities. Best management practices are practiced to control and collect spillage of release agents. Batch plants are often located in conjunction with gravel mining operations. This increases the potential for pollutants to affect underlying ground water. Trucks, loaders and other equipment are common on site. Spills and leaks from associated equipment in the manufacturing and delivery process pose a significant potential to contaminate waters of the state. In addition to good housekeeping and best management practices to minimize spills and leaks, facilities often channel stormwater to avoid contamination or remove oil by skimming it off the surface or through use of oil/water separators. Portable hot mix asphalt batch plants pose the same environmental concerns as permanent facilities. However, there is often very little lead-time before they must begin operation at a site and they are typically only at the site for a short period. The short notice and transient nature of these facilities create different permitting considerations for these facilities but they must still be able to assure compliance with permit conditions for asphalt batch plants. STORMWATM In some areas of the state, stormwater is a significant source of water at a facility. All parts of the state will occasionally receive significant rainfall events. Implementation of best management practices (BMPs) for stormwater management is required by the proposed permit. The most important BMP that relates to stormwater is minimization of the amount of stormwater which contacts products and raw materials or flows or falls into an area of active processing or process water storage. Page 6 r FACT SHEET many non-compliance issues during the first years of coverage were related to failure to understand permit requirements. There were around 350 warning letters and calls,mostly to prompt permittees to submit discharge monitoring reports as required by the current permit. In addition to warnings there were about 80 notices of violation/correction, 20 orders, and 30 civil penalties issued. Since the current permit included a compliance schedule, data from discharge monitoring reports (DMRs) during the first years of the current permit are not representative of how well the industry is doing with BMPs and treatment facilities in place. Therefore, only DMR data since January 1997 were evaluated for compliance with the current permit limits. DMR data during this time period was not available for all permitted sites. Sites that were inactive during this period most likely did not submit any monitoring reports. The current permit set limits on pH for discharges to ground water, in the range of 6.5 to 8.5, and for discharges to surface water, in the range of 6.0 to 9.0. Approximately 150 permittees had at least one apparent violation of pH. This amounted to 41 violations out of 961 data entries (=4%) for surface water discharge and 611 out of 5084 data entries (--9%) for discharge to ground water. Concrete batch plants account for about 62% of the apparent violations, asphalt batch plants about 15%, and all other categories about 23%. All discharges of process water to surface water had a limit for total suspended solids. The limit for the industrial sand category was 25 mg/1 monthly average and all other categories were 40 mg/1 monthly average. There were no violations from the two industrial sand facilities. There were 25 apparent violations in the other categories from 10 facilities. All discharges to surface water had a limit for turbidity of 50 NTU. This included process water, mine dewatering water, and stormwater. About 42 permittees had at least one violation of turbidity. This amounted to 112 apparent violations out of 648 data entries (=17%). WASTEWATER CHARACTERIZATION Characterization of the wastewater is considered for the industry as a whole and is based on discharge monitoring data submitted to Ecology from January 1, 1997 through January 1, 1999. The proposed wastewater discharge was characterized for the following parameters: Page 8 FACT SHEET Contaminant Source Hydrocarbons Spills or leaks from equipment and storage tanks (oil and grease, Maintenance shop hydraulic fluid, Hot mix asphalt plant wet scrubber and fuels) Delivery truck and equipment washing, release agent application Nitrate Blasting residues Concrete admixtures Turbidity Processing wastes Suspended solids Seepage from working face Dissolved solids Stormwater runon and runoff from disturbed areas Washing, screening, or crushing rock Stripping and digging operations Runoff from overburden,waste piles, and stockpiles Dust suppression Wet scrubber wastes Vehicle washing and cleanout Alkalinity(high pH) Concrete truck wash water Concrete batch pl?.nt water Chlorides Concrete admixtures Sulfates Concrete admixtures Ligninsulfonate Dust suppression Most of the listed contaminants have sources common to all the activities covered under the proposed permit. Some parameters such as sulfates,however, are only associated with specific industrial activities. All the covered activities have stormwater discharge,many also have process water discharge, and a few have mine dewatering water discharge. It is'important for the permittee to recognize the sources of contaminants and implement specific treatment technologies and BMPs for the type of discharge. Segregating process water from stormwater and relatively clean mine dewatering water, for example,can reduce the volume of water that requires treatment before discharge. Likewise, source control BMPs such as covered storage areas can reduce treatment requirements by preventing contamination. Selection of Pollutant Parameters The previous permit included limits for turbidity,pH, and total suspended solids. Additional monitoring was required for oil and grease, total petroleum hydrocarbons, alkalinity,total dissolved solids, nitrates,chlorides, and sulfates. Based on the collected data, only turbidity,pH, total suspended solids, and total dissolved solids were shown to be pollutants of concern and will be included in the revised permit. Temperature has been added as a parameter of concern for discharges to surface water. Temperature,turbidity, iron and manganese were also considered as potential parameters of concern for impacts on ground water quality. Page 10 FACT SHEET provides the basis for Ecology to require installation of ground water monitoring wells if site specific conditions warrant it. Total Dissolved Solids (TDS) are a gross measure of the amount of soluble pollutants in the wastewater. TDS can be detrimental to aquatic organisms in fresh water systems and unless significant and immediate dilution is available,it may cause unacceptable degradation. TDS can also contaminate ground water and violate drinking water standards. Because the data suggest that discharges from concrete batch plants can have elevated levels of TDS,these facilities will be required to monitor their process water discharges for TDS. There is also evidence that discharges of process water from asphalt batch plant wet scrubbers can have high levels of TDS. These discharges will also require monitoring for TDS. Iron and Manganese are regulated in drinking water to avoid unpleasant tastes and stains. These substances can be found in association with mined materials but are typically in their stable oxidized state and are not readily soluble. Mining activities do not typically create the conditions that would alter this state and cause iron and manganese enter ground water. Low pH is one condition that could result in dissolving iron and manganese but the permit limit of 6.5 to 8.5 for ground water discharges should be protective. Therefore,monitoring for iron and manganese is not required in the proposed permit. Oil and grease includes thousands of organic compounds with varying physical and chemical properties. Oil and grease exhibit an oxygen demand. Oil may adhere to fish gills or coat and destroy algae or other plankton. Oil will also taint the flesh of fish and shellfish. Some types of oils have been found to be toxic to aquatic organisms at concentrations as low as 0.1 mg/l. The current general permit required sampling and laboratory analysis for oil and grease. The data from this monitoring suggest that ongoing sampling is not necessary. The new permit will not include sampling discharges for oil and grease but does emphasize best management practices to prevent oil and grease from becoming part of any wastewater discharge. The permit also requires visual monitoring for the presence of an oil sheen. Total Petroleum Hydrocarbons (TPH)are often considered a subset of oil and grease. TPH measurements exclude that portion of oil and grease which consists of animal and plant oils and fats. Petroleum derived fuels and oils,the more toxic constituents, are measured by the TPH test. The TPH test also quantifies the lighter types of fuels, such as gasoline and diesel fuel,which escape detection in the usual oil and grease test. The existing general permit required sampling and laboratory analysis for total petroleum hydrocarbons. The data from this monitoring suggest that ongoing sampling is not necessary. The new permit will not include sampling discharges for TPH but does emphasize best management practices to prevent petroleum hydrocarbons from becoming part of any wastewater discharge. The permit also requires visual monitoring for the presence of an oil sheen. Temperature increases and decreases for process water,mine dewatering water, and stormwater are primarily a result of ambient air temperature and solar influences. Processing by the facilities covered under this permit does not typically transfer significant thermal energy. Temperature decreases have not been identified as a significant environmental concern but there are more than 300 rivers in the state that are listed for water quality temperature excursions as a result of high temperatures. The temperature of discharges to surface water during the warm weather months are therefore a concern. The temperature of discharges to ground water, are not expected to be Page 12 FACT SHEET were not in operation before August 6, 19991. A new source discharger must complete the SEPA process prior to application for coverage under the proposed general permit. Any existing facility planning a significant process change must submit a new application for coverage to modify their permit and demonstrate that the proposed change has complied with SEPA review. A significant process change for this industry group would be any modification of the facility that would change the characteristics of the discharge or include for coverage a new activity(SIC) that was not previously covered. There are no easily defined thresholds for what constitutes a change in the characteristics of the discharge other then when a facility adds a new activity (SIC) such as a concrete batch plant to their permitted activities. Other changes are not so easily defined. For instance, a change in the characteristics of the discharge is not necessarily just a change in the volume of the discharge. However, if a modification of the facility resulted in a discharge to surface water where previously no surface water discharge occurred, then a permit modification and SEPA review would likely be required. Facilities should notify their permit manager of any planned change and the potential to impact their wastewater discharge. The permit manager will determine if a permit modification and SEPA review is required. PROPOSED PERNUT LIMITATIONS Federal and State regulations require that effluent limitations set forth in a NPDES permit must be either technology-based or water quality-based. Technology-based limitations are based upon the treatment methods available to treat specific pollutants. Technology-based limitations are set by regulation or developed on a case-by-case basis (40 CFR 125.3, and Chapter 173-220 WAC). Water quality-based.limitations are based upon compliance with the Surface Water Quality Standards (Chapter 173-201A WAC), Ground Water Standards (Chapter 173-200 WAC), Sediment Quality Standards (Chapter 173-204 WAC) or the National Toxics Rule (Federal Register, Volume 57,No. 246,Tuesday,December 22, 1992). The more stringent of these two limits must be chosen for each of the parameters of concern. Each of these types of limits is described in more detail below. BACKGROUND The sand and.gravel general permit provides coverage for discharges to ground water as well as to surface water. About 150 permittees have a discharge to surface water and about 650 permittees only discharge to ground. Permittees on the west side of the mountains are much more likely to have a surface water discharge than those on the east side. Although water quality concerns for the state's ground water and surface water are not truly separate and distinct, there are potential differences in the fate of pollutants traveling to ground water versus direct discharge to surface water. Some of these differences are reflected in the current permit with additional monitoring parameters for those discharges to surface water(e.g.turbidity). Because of these differences, water quality-based considerations will consider ground water discharges and surface water discharges separately. 1 This is the intended effective date of the proposed permit. Portable facilities were not included as a separate category in the current permit. Therefore,the effective date of the proposed permit applies to these facilities. Page' 14 y t FACT SHEET solids which would otherwise clog piping, damage pumping equipment, and contaminate the product. The EPA report Suspended Solids Removal in the Crushed Stone Indusgy was examined to ascertain the degree of effluent reduction capability within the industry. The pollution control technology examined was settling and recycle or reuse. The report summarized a variety of conditions and waste streams and the attainable TSS limit for each. The nonrain categories are appropriate for consideration of the process wastewater since the proposed general permit requires that stormwater should be segregated from process water unless the facility can treat stormwater to the process wastewater limits. The level of effluent quality attainable for non- rainfall conditions,including all facilities and all wastewater streams (excluding stormwater)is reported as a monthly average TSS of 38 mg/1 and a maximum daily TSS of 80 mg/l. The limit proposed for most categories of this proposed general permit is 40 mg/1 average monthly TSS and 80 mg/l maximum daily TSS. The TSS encountered in the process water has a rapid settling rate. TSS removal efficiencies range from 90% with very dilute waste streams to over 99% for the typical process waste streams. Despite the relatively high TSS loadings, the material settles easily,and the limits of 40/80 mg/l TSS will be satisfied so long as adequate settling time and proper design and operation are maintained. Monthly average limits and daily maximum limits are constructed that alert the facility and Ecology to instances where pollution prevention has failed. The limits recognize that occasional excursions in excess of the average can occur. Ecology, consistent with federal policy and regulation,has chosen to specify limits that define the limit of performance that can reliably be achieved. However,when only one sample is taken in a given month,that sample becomes the monthly average, subject to the more restrictive monthly average limit. Hot mix asphalt plants and facilities covered under the industrial sand category must meet more stringent effluent guidelines established as BPT and BAT by the federal government. Asphalt Concrete facilities,in accordance with 40 CFR Part 443, Subpart B, must not discharge any process wastewater pollutants to surface waters of the state. Industrial sand facilities, in accordance with 40 CFR Part 436, Subpart D,must recycle at least a portion of the wastewater and not exceed the following limitations for discharge of process water and mine dewatering: 45 mg/1 TSS daily maximum and 25 mg/l TSS for a monthly average. The previous permit established a surface water discharge water quality-based limit for turbidity of 50 NTU. In most instances,this limit was more protective of the water quality than TSS. While the data are not sufficient to replace TSS monitoring with turbidity monitoring,they are sufficient to reduce the frequency of TSS monitoring in favor of turbidity testing. Stormwater Discharge Conditions The TSS in stormwater from these facilities must be controlled by BMPs. As with all wastewater discharges,the technology-based requirements and water quality-based requirements must be satisfied. The BMPs such as detention and housekeeping are based on the federal determination that such BMPs constitute BATBCT for stormwater at this time (FR 40974, August 16, 1991). Page 16 FACT SHEET regulation designed to protect the beneficial uses of the surface waters of the state. Surface water quality-based effluent limitations may be based on an individual waste load allocation (WLA) or on a WLA developed during a basin wide total maximum daily loading study (TMDL). NUMERICAL CRITERIA FOR THE PROTECTION OF AQUATIC LIFE "Numerical" water quality criteria are numerical values set forth in the State of Washington's Water Quality Standards for Surface Waters (Chapter 173-201A WAC). They specify the levels of pollutants allowed in a receiving water while remaining protective of aquatic life. Numerical criteria set forth in the Water Quality Standards are used along with chemical and physical data for the wastewater and receiving water to derive the effluent limits in the discharge permit. When surface water quality-based limits are more stringent or potentially more stringent than technology-based limitations, they must be used in a permit. NUMERICAL CRITERIA FOR THE PROTECTION OF HUMAN HEALTH The U.S. EPA has promulgated 91 numeric water quality criteria for the protection of human health that are applicable to Washington State (EPA 1992). These criteria are designed to protect humans from cancer and other disease and are primarily applicable to fish and shellfish consumption and drinking water from surface waters. NARRATIVE CRITERIA In addition to numerical criteria, "narrative" water quality criteria(WAC 173-201 A-030) limit toxic,radioactive, or deleterious material concentrations below those which have the potential to adversely affect characteristic water uses,cause acute or chronic toxicity to biota, impair aesthetic values, or adversely affect human health. Narrative criteria protect the specific beneficial uses of all fresh(WAC 173-20 1 A-130) and marine (WAC 173-201 A-140) waters in the State of Washington. ANTIDEGRADATION The State of Washington's Antidegradation Policy requires that discharges into a receiving water shall not further degrade the existing water quality of the water body. In cases where the natural conditions of a receiving water are of lower quality than the criteria assigned, the natural conditions shall constitute the water quality criteria. Similarly,when the natural conditions of a receiving water are of higher quality than the criteria assigned,the natural conditions shall constitute the water quality criteria. More information on the State Antidegradation Policy can be obtained by referring to WAC 173-201A-070. The permit has been conditioned to implement the surface water quality standards and protect receiving water from degradation. A general permit,however,provides coverage for an industry group and site-specific conditions may exist that are not adequately addressed by the general permit. In these situations, either an administrative order or application for an individual permit may be necessary to protect the receiving water. The proposed permit has a water quality-based limit for turbidity. This limit was set assuming a dilution factor of 10 and a background turbidity level of 0 NTU. Under typical discharge Page 18 FACT SHEET CONSIDERATION OF SURFACE WATER QUALITY-BASED LIMTTS FOR Nummuc CRnERiA Pollutant concentrations in the proposed discharge may exceed water quality criteria with technology-based controls which Ecology has determined to be AKART. A mixing zone is authorized in accordance with the geometric configuration, flow restriction, and other restrictions for mixing zones in Chapter 173-201A WAC. The mixing zone authorized in this general permit is established as a ratio of one part wastewater discharge to nine parts surface water or a dilution factor of 10 in the chronic mixing zone. There were no parameters of concern that required consideration of acute effects. The water quality-based pH limits are in the range of 6.5 to 8.5 standard units. Considering typical receiving water conditions and a dilution factor of 10, the technology-based limits of in the range of 6.0 to 9.0 are more restrictive than water quality-based limits for pH. The water quality-based turbidity criteria for Class A waters is less than 5 NTU above background. Allowing a dilution factor of 10 and a background level of 0 NTU in the receiving water, a water quality-based limit of 50 NTU was assigned. A technology-based limit for turbidity has not been determined. The quantity and quality of the data submitted to date under the current permit are not sufficient to establish a technology-based standard for this industry group. Therefore the proposed permit sets a turbidity limit of 50 NTU based on water quality- based criteria. WHOLE EFFLUENT TOXICITY The Water Quality Standards for Surface Waters require that the effluent not cause toxic effects in the receiving waters. Many toxic pollutants cannot be detected by commonly available detection methods. However,toxicity can be measured directly by exposing living organisms to the wastewater in laboratory tests and measuring the response of the organisms. Toxicity tests measure the aggregate toxicity of the whole effluent, and therefore this approach is called whole effluent toxicity(WET)testing. Toxicity caused by unidentified pollutants is not expected in the effluent from this discharge as determined by the screening criteria given in Chapter 173-205 WAC. Therefore,no whole effluent toxicity testing is required in this permit. Ecology may require effluent toxicity testing in the future if it receives information that toxicity may be present in this effluent. HUMAN HEALTH Washington's water quality standards now include 91 numeric health-based criteria that must be considered in NPDES permits. These criteria were promulgated for the state by the U.S. EPA in its National Toxics Rule(Federal Register,Volume 57,No. 246,Tuesday,December 22, 1992). Ecology has determined that the discharge from this industry group is unlikely to contain chemicals regulated for human health, SEDMIENT QUALITY Ecology has promulgated aquatic sediment standards (Chapter 173-204 WAC)to protect aquatic biota and human health. These standards state that Ecology may require Permittees to evaluate the potential for the discharge to cause a violation of applicable standards (WAC 173-204-400). Page 20 FACT SHEET garbage but can also include use by recreational vehicles that may undo BMPs designed to minimize erosion. COMPARISON OF EFFLUENT LIMITS WITH THE EXISTING PERMIT There have been no changes in effluent limits in the proposed permit. The review of data from monitoring requirements in the current permit did not suggest that additional limits were applicable. Data did confirm that existing limits are necessary and should be continued. MONITORING REQUIREMENTS Monitoring,recording, and reporting are required(WAC 173-220-210 and 40 CFR 122.41)to verify that the treatment process is functioning correctly and the effluent limitations are being achieved. Pennittees that discharge to surface water are also required to monitor temperature during the summer months to determine if there is any reasonable potential to violate water quality temperature standards. Discharges associated with concrete batch plant process water must also monitor for total dissolved solids. The monitoring schedule is detailed in the proposed permit under Special Condition SA. Specified monitoring frequencies take into account the quantity and variability of the discharge, the treatment method,past compliance by the industry as a whole, significance of pollutants, and cost of monitoring. REPRESENTATIVE SAMPLING Monitoring is intended to verify how well control measures are working to assure compliance with discharge limits. The proposed permit requires that monitoring must be representative of the operating conditions at a site and the nature of discharges that occur. Representative sampling of discharges to ground water does not mean that all ponds and puddles that occur onsite must be sampled. It does mean that the Permittee must identify how many samples are necessary to accurately represent discharge conditions. If all the ponds and puddles onsite have the same pH, one sample will typically be representative of the site. If pH at ponds and puddles in one area of a site are typically higher or lower than the rest of the-site, more than one sample must be taken. The proposed permit requires a monitoring plan. The plan should include documentation of the testing conducted by the Permittee to determine representative sampling for their site. The Pen-nittee should periodically conduct additional sampling to assure that their monitoring plan provides representative sampling. Stormwater discharges to surface water pose another problem for representative sampling. Since storm events are not under the control of the Permittee, discharges may occur at any time of day or night and with varying intensity. The intent of monitoring for turbidity is to determine if control measures are adequate to control discharge turbidity. To achieve this sampling should be conducted during a major storm event when control measures are most stressed. Since this cannot be predicted in advance,the proposed permit requires two samples a month, increasing the odds that some samples will be taken during the most significant storm events of a month. It is acceptable for the Permittee to sample twice during one storm event if the duration of the storm event is sufficient to allow at least 24 hours between sampling. Page 22 FACT SHEET event with a probable reoccurrence interval of once in ten years (design storm). This is consistent with federal regulations regarding these industries. This condition addresses the use of chemical additives for wastewater treatment or erosion control. Typically these include chemicals to enhance solids settling in retention ponds or promote soil stabilization. Many of these chemicals are used in the drinking water industry and therefore are typically considered to be "safe". However, some do demonstrate aquatic toxicity and others have not even been tested to determine aquatic toxicity. The proposed permit includes restrictions on the use of these chemicals to minimize the potential for any harmful effects on water quality from their use. Direct discharge of wastewater from a hot mix asphalt plant or a concrete batch plant into an aquifer is prohibited in order to protect drinking water supplies. Wastewater from maintenance shop is regulated to prevent discharge of pollutants. The use of ligninsulfonate is restricted due to the high biochemical oxygen demand (BOD) of the material and the potential for polluting ground Nvater or surface water from road runoff. Otherwise, a BOD limitation and monitoring would be required to restrict its pollution potential in surface water and ground water. This condition also regulates the discharge to gravel pit ponds. Gravel is often extracted below the water table and when extraction is completed, a pond remains behind. Some facilities then use the pond as'a settling basin for stormwater and/or process water. However, gravel pit ponds may be considered as waters of the state. Untreated stormwater and process water would not likely meet surface water criteria for turbidity. This sets up a potential conflict because the addition of sediment laden wastewater adds fines to the gravel pond which can be a desirable part of reclamation. The fines help seal the pit and in more shallow areas provide a substrate for plants. As a part of a reclamation plan, using the pond as a settling basin may be desirable. The proposed permit defines the period of reclamation as part of the mining process and authorizes solids settling in the pond as long as it is part of an approved reclamation plan. STORMWATER POLLUTION PREVENTION PLAN All facilities must have a completed Stormwater Pollution Prevention Plan(SWPPP). The SWPPP must be retained on-site or within reasonable access to the site and available,upon request, to Ecology. The SWPPP must be developed and implemented to identify and control stormwater pollution by industrial activities. The objectives include: elimination of commingling of process water and stormwater, implementation of best management practices (BMPs), and the prevention of the violation of water quality standards. The proposed permit requires ongoing wet and dry season investigations to determine if there is commingling of stormwater with process water. Best management practices (BMPs) are a very significant part of complying with permit conditions. BMPs include schedules of activities, prohibitions of practices, maintenance procedures, and other physical, structural and/or managerial practices to prevent or reduce the pollution of waters of the State. BMPs include treatment systems, operating procedures, and practices used to control plant site runoff, spillage or leaks, sludge or waste disposal, and drainage from raw material storage. In this permit, BMPs are further categorized as operational, source control, erosion and sediment control, and treatment. Page 24 FACT SHEET The discharge of stormwater to any sanitary sewer is prohibited. This is necessary to limit both the dilution of sanitary wastewater and the hydraulic loading of sanitary sewers and treatment plants. SPILL PLAN It is typical for the industrial activities covered under this permit to include storage of chemicals that have the potential to cause water pollution if accidentally released. Fuel,hydraulic fluid and other petroleum products are commonly stored onsite and heavy equipment and trucks contain significant quantities of these materials. Spills can and do happen at these sites. As discussed previously, mining sites are particularly vulnerable to ground water contamination. This permit requires the Permittee to develop best management plans to prevent accidental release of these substances and to respond quickly to clean up spills that do occur. These requirements are consistent with section 402(a)(1) of the Federal Water Pollution Control Act(FWPCA) and RCW 90.48.080. The Permittee must develop,implement, and maintain a spill plan to prevent the accidental release of pollutants to state waters and to minimize damages if such a spill occurs. This plan must be kept onsite or within reasonable access to the site and made available to Ecology upon request. SOLID WASTE DISPOSAL The Permittee is required to properly dispose of solid wastes and comply with the applicable solid and hazardous waste regulations (Chapters 173-303 and 173-304 WAC). Collection, separation, and settling are some of the techniques for controlling stormwater or process water that may result in the generation of solid wastes. The solid waste from the activities covered under this permit will most often contain no hazardous waste materials and may be used as soil or fill material. However,it is the Permittee's responsibility to verify that the solid waste is properly identified, handled and disposed of. Solid waste from concrete truck washout for instance, may have a high pH and leachate from stock piles of this material may have a potential to pollute waters of the state. The small particulate matter(fines) that is removed from air emissions during the production of asphalt may contain pollutants of concern and should be evaluated for toxic substances to determine appropriate disposal options. GENERAL CONDITIONS General Conditions are based directly on state and federal law and regulations and have been standardized for all individual industrial NPDES permits issued by Ecology. Condition G 1 requires the Permittee to comply with the terms and conditions of the proposed permit. Condition G2 requires the Permittee to properly operate and maintain all pollution control facilities and systems. Condition G3 requires the Permittee to control its production in order to maintain compliance with its permit. Condition G4 requires the Permittee to inform Ecology of any wastewater system bypass. Condition G5 requires the Permittee to allow Ecology to access the treatment system, production facility, and records related to the proposed permit. Condition G6 requires the Permittee to submit a new application for coverage prior to implementing significant changes in covered activities. Condition G8 specifies conditions for modifying, suspending or terminating the permit. Condition G9 requires the permittee to notify Ecology when facility changes may require modification or revocation of permit coverage.

The proposed permit contains conditions and effluent limitations which are described in the rest of this fact sheet. On June 15, 1998,Ecology announced that it intended to update and reissue the NPDES and state waste discharge general permit known as the sand and gravel general permit. A letter was sent to current permittees,construction materials mining operations as identified from Department of Natural Resources data, interested parties identified in the initial permit issuance, and to parties with standing requests for Ecology announcements. The announcement was also included in Ecology's Summer edition of Confluence and posted under Ecology's home page on the Internet. The mailing included a response card allowing recipients to request updates on permit developments and to volunteer for the advisory group. Ecology will publish a Public Notice of Draft(PNOD) on May 5, 1999 in the State Register,the Spokesman Review, the Seattle Daily Journal of Commerce, the Daily Olympian, and the Yakima Herald Republic to inform the public that the draft permit and fact sheet are available for review. The notice will also be mailed to all parties identified above as interested parties. Interested persons are invited to submit written comments regarding the draft permit. The.draft permit, fact sheet, and related documents are available for inspection and copying between the hours of 8:00 a.m. and 5:00 p.m. weekdays,by appointment, at Ecology's regional offices listed below. Written comments should be mailed to: Keith Johnson,Water Quality Program Department of Ecology PO Box 47600 Olympia,WA 98504-7600 Ecology will also conduct a workshop and public hearing at four locations around the state.

Page 30 FACT SHEET APPENDIX B--GLOSSARY Acute Toxicity--The lethal effect of a compound on an organism that occurs in a short period of time,usually 48 to 96 hours. AKART--An acronym for"all known, available, and reasonable methods of treatment". Ambient Water Quality--The existing environmental condition of the water in a receiving water body. Ammonia--Ammonia is produced by the breakdown of nitrogenous materials in wastewater. Ammonia is toxic to aquatic organisms, exerts an oxygen demand, and contributes to eutrophication. It also increases the amount of chlorine needed to disinfect wastewater. Average Monthly Discharge Limitation--The average of the measured values obtained over a calendar month's time. Best Management Practices (BMPs)--Schedules of activities,prohibitions of practices, maintenance procedures, and other physical, structural and/or managerial practices to prevent or reduce the pollution of waters of the State. BMPs include treatment systems, operating procedures, and practices to control: plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage. BWs may be further categorized as operational, source control,erosion and sediment control, and treatment BMPs. BOD5--Determining the Biochemical Oxygen Demand of an effluent is an indirect way of measuring the quantity of organic material present in an effluent that is utilized by bacteria. The BOD5 is used in modeling to measure the reduction of dissolved oxygen in a receiving water after effluent is discharged. Stress caused by reduced dissolved oxygen levels makes organisms less competitive and less able to sustain their species in the aquatic environment. Although BOD is not a specific compound,it is defined as a conventional pollutant under the federal Clean Water Act. Bypass—The intentional diversion of waste streams from any portion of a treatment facility. Chlorine--Chlorine is used to disinfect wastewaters of pathogens harmful to human health. It is also extremely toxic to aquatic life. Chronic Toxicity--The effect of a compound on an organism over a relatively long time, often 1/10 of an organism's lifespan or more. Chronic toxicity can measure survival, reproduction or growth rates, or other parameters to measure the toxic effects of a compound or combination of compounds. Clean Water Act (CWA)--The Federal Water Pollution Control Act enacted by Public Law 92- 500, as amended by Public Laws 95-217, 95-576, 96-483,97-117;USC 1251 et seq. Compliance Inspection -Without Sampling—A site visit for the purpose of determining the compliance of a facility with the terms and conditions of its permit or with applicable statutes and regulations. Page 32 a � FACT SHEET Maximum Daily Discharge Limitation--The highest allowable daily discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. The daily discharge is calculated as the average measurement of the pollutant over the day. Method Detection Level (MDL)--The minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is above zero and is determined from analysis of a sample in a given matrix containing the analyte. Minor Facility--A facility discharging to surface water with an EPA rating score of< 80 points based on such factors as flow volume,toxic pollutant potential, and public health impact. Mixing Zone--An area that surrounds an effluent discharge within which water quality criteria may be exceeded. The area of the authorized mixing zone is specified in a facility's permit and follows procedures outlined in state regulations(Chapter 173-201A WAC). National Pollutant Discharge Elimination System(NPDES)--The NPDES (Section 402 of the Clean Water Act)is the Federal wastewater permitting system for discharges to navigable waters of the United States. Many states,including the State of Washington, have been delegated the authority to issue these permits. NPDES permits issued by Washington State permit writers are joint NPDES/State permits issued under both State and Federal laws. pH--The pH of a liquid measures its acidity or alkalinity. A pH of 7 is defined as neutral, and large variations above or below this value are considered harmful to most aquatic life. Quantitation Level (QL)--A calculated value five times the MDL(method detection level). Responsible Corporate Officer—A president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy-or decision-making functions for the corporation, or the manager of one or more manufacturing, production,or operating facilities employing more than 250 persons or have gross annual sales or expenditures exceeding$25 million (in second quarter 1980 dollars), if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures(40 CFR 122.22). Technology-based Effluent Limit--A permit limit that is based on the ability of a treatment method to reduce the pollutant. Total Suspended Solids (TSS)—Total suspended solids is the particulate material in an effluent. Large quantities of TSS discharged to a receiving water may result in solids accumulation. Apart from any toxic effects attributable to substances leached out by water, suspended solids may kill fish, shellfish, and other aquatic organisms by causing abrasive injuries and by clogging the gills and respiratory passages of various aquatic fauna. Indirectly, suspended solids can screen out light and can promote and maintain the development of noxious conditions through oxygen depletion. State Waters--Lakes,rivers,ponds, streams, inland waters,underground waters, salt waters, and all other surface waters and watercourses within the jurisdiction of the state of Washington. Stormwater--That portion of precipitation that does not naturally percolate into the ground or evaporate,but flows via overland flow,interflow,pipes, and other features of a stormwater drainage system into a defined surface water body,or a constructed infiltration facility. Page 34 e � FACT SHEET APPENDIX C--ADVISORY GROUP An advisory group was formed from volunteers to provide information,comments, and suggestions relevant to rewriting the sand and gravel general permit. Although Ecology had the responsibility to implement the applicable law and write the permit,the advisory group had a significant role in improving the quality and completeness of the finished permit. The participants were expected to put forth positive suggestions and criticism based on their personal knowledge and expertise and to provide representation of the larger community,for example; local government perspective, environmental advocates, or impacts to large or small businesses that are covered by this permit. The advisory group met four times: September 29, 1998 Lacey, Washington Orientation and Presentation of Issues November 18, 1998 Yakima,Washington Issues and Concerns Discussion January 11, 1999 Lacey,Washington Review of Draft Permit February 8, 1999 Bellevue,Washington Final Review of Draft permit Members were selected to provide as balanced a representation of the interested parties as possible from those that volunteered. More than.70 individuals had indicated an interest in serving on the advisory group but the group was limited to 17 participants to maintain a manageable and participatory size. Geographical location, experience in sand and gravel issues, and ability to represent a larger constituency were considered in the selection. The members of the advisory group were: Name Address Comments Randy Baer Superior Asphalt& Concrete Randy is an environmental/compliance manager (509) 248-6823 PO Box 10268 for Superior Asphalt&Concrete; responsible for supedor@ewa.net Yakima,-WA 98909 compliance with air,water,and mining permits.

Page 36 FACT SHEET APPENDIX D--RESPONSE TO COMNENTS Ecology announced the draft sand and gravel general permit and fact sheet on May 5, 1999. The public comment period ended on June 15, 1999. Four public hearings were held: Spokane,June 7, 1999; Yakima,June 8, 1999;Bellevue,June 11, 1999; and Lacey, June 14, 1999. A synopsis of the comments received and the public testimony provided is provided below along with Ecology's response. Quotation marks are used wherever the exact text of the comment or testimony is used. Permit Revisions: ➢ Table of Contents was updated to include the missing third level headings. ➢ S1.D.1.d.was: Any facility that is not covered by a DNR reclamation permit and uses materials that are not inert for reclamation or backfill; or Changed to: Any facility that uses materials that are not inert for reclamation or backfill and also is not covered by a DNR reclamation permit; or ➢ S2.A.2. was: All new facilities...

No discharge is authorized until the effective date of permit coverage as provided in Special Condition S2.E. ... ➢ SIG. Portable Facilities was: An owner and/or operator of a portable concrete batch plant, portable asphalt batch plant, or portable rock crusher may apply for coverage under this general permit for the portable facility. Coverage will apply only to the specific portable facility identified in the application for coverage and will authorize operation of the portable facility throughout the state subject to the following requirements: Page 38 FACT SHEET cannot safely sustain permanent damage through depletion or an impairment of the beneficial use of the ground water arising from a modification of the water quality and quantity." Response: WAC 173-154-050 deals with impacts resulting from ground water withdrawals. It has no direct bearing on wastewater discharge requirements. The permit excludes from coverage any facility where the pit design will intercept more than one aquifer because there are no permit conditions to address the potential of one aquifer to contaminate another independent of the potential of mining activities to cause pollution. The permit,however, does provide protection of ground water from pollution resulting from the mining activities and hence protects any lower level aquifers that may be naturally connected. The permit also excludes from coverage any facility that"would impair adjacent water rights as a result of pit operations lowering the water table." While Ecology appreciates the concern expressed by the comment, we do not believe that it would add to the effectiveness of the permit. No change to the permit. Comment 3: (S LD.1.b. and S 1.D.1.c.) "Eventually all waters (soon)will have plans and restrictions (TMDL). Not industry exclusive pollutants. .:. Ecology MUST consider cumulative water quality problems. Against state law to pollute already impaired waters." Comment proposes to broaden the exclusion from coverage language in these provisions to: (S LD.Lb.) "The facility discharges to a water body that is impaired,through cumulative testing, by at least one or combination of pollutants." (S LD.l.c.) "Any facility that discharges to a water body listed pursuant to Section (303)(d) of the Clean Water Act." Response: There may be some misunderstanding about how S LD.Lb. and S LD.1.c. address the concerns of a listed water body or one regulated through Total Maximum Daily Load(TMDL) allocations. A water body is listed under the Clean Water Act Section 303(d) when there is evidence that its beneficial uses are threatened or impaired by one or more pollutants. The listing is for specific parameters (pollutants). Likewise, a TMDL is typically conducted to address the specific parameters that threaten the beneficial use of the water body. Requirements to restore beneficial uses may be more restrictive discharge limits for the identified parameters than would typically be applied. Such specialized restrictions would be out of the scope of this general permit. There are specific pollutants of concern associated with those facilities covered under the sand and gravel general permit. These parameters (pollutants)were identified based on an analysis of industry activities and include pH, petroleum products, and suspended solids. When the parameters (pollutants) of the listed water body or water body subject to TMDL allocations coincide with parameters of concern identified for this industry, then coverage under the general permit is excluded unless the conditions in the general permit are sufficiently protective. Additional environmental protection would not result from requiring an individual permit for parameters not identified by the TMDL or Section 303(d)listing of a water body because the general permit conditions are protective and consistent with legal requirements. No change to the permit. Comment 4: (S 1.D.1.d.) It was not clear what the intent was of this exclusion and whether"control plan"means the same as "environmentally sensitive". Page 40 S � FACT SHEET Response: S I.F. conditions the cancellation of a permit for a site that intends to permanently cease operation. The comment proposes expanding the intent to include canceling the permit for a facility that implements "zero discharge". This proposal is related to Comment 1 and the response to Comment 1 also applies here. The permit addresses the requirements for facilities with a discharge. There is no special language required in the permit to allow cancellation of a permit if the legal requirement for a discharge permit no longer exists. If the facility is modified to discharge completely to a sanitary sewer, a discharge still exists and there are state and federal pretreatment requirements. There is still a permit requirement and the modification may be problematic as WAC 173-216-060(b)(vii)prohibits discharge of stormwater to a sanitary sewer. No change to the permit. Comment 7: "S 1.D.d. A facility is Excluded from coverage when Not covered by a DNR reclamation permit. However,in S 1F Termination of coverage is defined for facilities Not covered by a DNR reclamation permit. How can a facility request termination of coverage when it is Excluded from coverage?" Response: There is an apparent miscommunication here. S 1.13.1.d. excludes from coverage any facility that is not covered by a DNR reclamation permit and uses materials that are not inert for reclamation or backfill. The exclusion here relates to sites where both conditions exist; the use of materials that are not inert and not subject to DNR reclamation. When DNR is in charge of reclamation, this exclusion is not required. Sites not subject to DNR reclamation must either use inert materials for reclamation or backfill (thus eligible for coverage under the general permit)or they must request an individual permit that can address the use of materials that are not inert. S LF. defines the requirements for termination of permit coverage for facilities that are covered by a DNR reclamation plan and those not subject to DNR reclamation. Revision of the permit language might improve readability and clarity and therefore S 1.D.1.d. will be changed to read: "Any facility that uses materials that are not inert for reclamation or backfill and also is not covered by a DNR reclamation permit;" S2. Coverage Requirements Comment 8: "Our Association believes that receiving water quality should not be limited _ to industry specific pollutants. We believe that DOE has an ethical responsibility to the people of the state who depend on ground water for their potable drinking water. By limiting receiving water quality to industry specific pollutants,Ecology may be inadvertently applying(cumulatively)more "Load" to a water supply than it can take. We understand that TMDLs are in the development stages and are not implemented into the permitting process to date. But the technology and knowledge are understood and should be a part of this permitting process. In the best interests of"Public Health and Safety" and "The Protection of the Environment",Ecology, as the known expert on water quality,must set the proper parameters to ensure the future availability of clean, safe drinking water to the people of the State." The comment proposes adding additional language: "When an applicant applying for a new proposal covered under the general permit. Receiving water quality must be addressed, at the applicants expense. If it is found that the receiving water cannot, in the Page 42 tl � FACT SHEET certain defined activities of a given industry. It is for this reason the discretionary application should be narrowed not broadened, as they are applicable to many entities. We urge you to remove any ambiguity in the permit content and remove the subjectivity of decision making by permit managers as it can be construed as arbitrary and subject to individual permittee appeal." Response: These conditions comply with regulatory requirements found in WAC 173- 226-130(5) and WAC 173-226-200(3)(f). The pertinent regulatory language is "...for operations previously under permit for which an increase in volume or change in the character of the effluent is requested over that which was previously authorized...". In addition,federal law,40 CFR Part 122.41(L)(1)(i-ii), requires notice when"...alteration or addition could significantly change the nature or increase the quantity of pollutants..." The permit implements the law through requirements triggered by"significant process change". Ecology agrees that the definition of significant process change found in the permit is open to interpretation but we believe it provides the appropriate framework for evaluating a change and making a determination. It is the permittee's responsibility to notify Ecology of proposed changes that could result in a change in the characteristics of the discharge and it is Ecology's responsibility to determine if the proposed change constitutes"significant process change". Ecology permit managers do share information and meet on occasion to address issues such as what constitutes significant process change. At a recent meeting permit managers agreed to the following guidance: The test is the potential of a change in operations to impact the environment. Some changes such as addition of industrial activity (SIC) or addition of a new type of discharge are typically considered a significant process change. Other changes at a facility typically require case by case evaluation. If a permittee does not agree with an Ecology decision,they may request reconsideration and all decisions may be appealed. It may not be a perfect system but to replace "best professional judgement"by defining exactly what changes are a significant process change will not be perfect either. No change to the permit. Comment 11: (S2.G.) "The permit authorizes the discharge,not the operation of the portable facility. Please change `authorized to operate' to authorized to discharge." Response: The point of this comment is well taken. The language will be changed to read as follows: An owner and/or operator of a portable concrete batch plant,portable asphalt batch plant, or portable rock crusher may apply for coverage under this general permit for the portable facility. Coverage will apply only to the specific portable facility identified in the application for coverage. Permit coverage is provided for the portable facility at sites throughout the state subject to the following requirements: The language of S2.G.1. will also be changed from `A portable facility will be authorized to operate at a site for a limited time,not to exceed one (1) year...',to: Page 44 I FACT SHEET Comment 14: "The discharge turbidity limit of 50 NTU contained in the draft permit, is neither a water quality, nor,technology based limit. It is more stringent than the requirements of the Surface Water Quality Standards and does not provide compensation for background conditions. During flooding events, dischargers would be required to retain and treat flood water. This is an onerous situation for most retention facilities, guaranteeing violations. ... It is recommended the limits specified in the Water Quality Standard be substituted for '50 NTU'." Comment 15: (S3.A.) "...the original permit was based on the factor of tenfold dilution in the receiving waters and that's how that 50 effluent limit was originally established for turbidity, the NTUs being 50 NTUs for surface water discharges. So therefore those facilities which do not have a tenfold dilution where they are discharging their effluent really were not intended to be covered by the general permit in the first place, and so therefore it's important that those facilities that are currently covered by this general permit verify through sampling that they're able to comply with water quality standards." Response: (comments 13, 14, and 15) A discharge permit, individual or general,cannot authorize a discharge in violation of surface water quality standards other than within the context of a compliance schedule to achieve water quality standards. An individual permit is able to address the site-specific conditions both in terms of the discharge and the receiving water and can readily implement compliance through permit conditions. A general permit,however,must define the characteristics of the discharge and receiving water of the targeted industry group as a whole and does not easily accommodate major differences in site-specific conditions. This makes applying water quality-based requirements to permit conditions a more difficult task. The surface water quality standards limit turbidity in discharge water based on the type-of receiving water. The types include, Class AA (extraordinary),Class A(excellent), Class B (good), Class C (fair), and Lake Class. There is no separate designation for wetlands but they are primarily to be protected through implementation of antidegradation procedures. Limits vary: a constant 5 NTU over background for Lake Class; 5 NTU over background or 10% over background when background exceeds 50 NTU for Class AA and Class A; 10 NTU over background or 20% over background when background exceeds 50 NTU for Class B and Class C. Regulation classifies some specific water bodies in chapter 173-201A but unclassified waters will most often default to Class A. Standards also allow the establishment of a mixing zone and the maximum size of the mixing zone is defined within site-specific conditions. Setting a turbidity limit in a general permit that applies to all facilities but takes into account all the site-specific variables of the regulation is a significant challenge. One way to achieve that end would be to simply state the surface water quality standard as the limit and require the permittee to achieve that limit at the point of discharge (end of pipe). This approach would not provide for a dilution zone and would still require site- specific information such as receiving water background levels to determine compliance. This approach could be modified to include a dilution zone but then it would be necessary to take samples in the stream at the edge of the authorized dilution zone as well as upstream from the point of discharge. Unless there is complete mixing of the discharge and the receiving water within-the dilution zone, identification of the Page 46 FACT SHEET the permit has language to address the situation. Special-Condition S 1.D.Lb. excludes from coverage any facility that discharges to a water body with a control plan that the general permit does not adequately address (includes restrictions for the protection of endangered species). Where special restrictions apply to a facility with coverage under this permit, General Condition G7 allows Ecology to revoke permit coverage and require application for an individual permit. In a telephone conversation, the Environmental Protection Agency(EPA),Region 10 office, indicated that the state action of issuing a general permit would not be subject to consultation. Since there is no federal decision, there is no nexus that would trigger a consultation. The EPA does receive a copy of the draft permit for review and comment. However,the EPA does not"approve" the general permit. Authority to issue individual and general permits is delegated to the state. No change to the permit. Comment 17: (SIA. and SIB.)DOE should take a closer look at the pH-testing requirement for sites that have asphalt activities and sand/gravel activities. It is a well know fact that concrete activities can contribute to an increase in pH, however, sites that do not have concrete activities should be given some reprieve in that testing. Response: It is true that the concrete industry expects to have high pH in process water and often will have to treat wastewater to adjust the pH before discharge. Monitoring here is essential to verify that treatment has been effective. However,in reviewing data collected under the original permit, pH excursions were not limited to concrete manufacturing facilities. While the data alone are sufficient to justify ongoing monitoring, monitoring for pH is also a reasonably inexpensive way to provide an ongoing indicator of site stability. Changes in pH can result from a change in source materials or from changes in site management and can provide an"early warning"system for developing problems. Once a month monitoring is not an unreasonable requirement for discharges of process water. Since the pH of stormwater can be altered by materials on-site,monthly monitoring for discharge to surface water and quarterly monitoring for discharges to ground water are also reasonable. No change to the permit. Comment 18: (SIA. and SIB.)The pH limits for surface water should be the same as it is for ground water. "... there is currently effluent limits for ground water that are different from the effluent on surface waters, and recognizing that extreme values of pH in surface waters can cause fish kills. I wanted to make sure that we reduce the effluent limit of pH to coincide with those limits that are required of ground water discharges. It is technologically feasible and the industry at large is having no trouble meeting those ground water criteria. Therefore,the industry at large can also accomplish the same degree of neutralization for surface water discharges and'therefore I wanted to support the notion that the effluent limits for surface waters ought to be equivalent to and equal to the effluent limits for ground water. Comment 19: (SIA. and SIB.)The pH limits for surface water and ground water should not be changed. These limits withstood the scrutiny of the stakeholder group that reviewed permit drafts and are appropriate. Response: (comments 18 and 19) There certainly is a"feeling" of logic that suggests that pH limits should be the same for discharges to surface water as they are for Page 48 FACT SHEET AKART may also be derived by consideration of the treatment performance of similar facilities. In examination of the data collected to date under the current permit,nearly half the facilities continue to have periodic pH excursions. Of those facilities with concrete batch activities,more than half experience periodic exceedences. At this time, the data are not supportive of a more restrictive AKART pH limit based on performance. Considering the federal and state regulatory precedent for a technology-based limitation for pH is in the range of 6.0 to 9.0 and the lack of convincing data to support a performance based AKART determination,the technology-based limit for surface water discharges, in the range of 6.0 to 9.0, will not be changed. No change to the permit. Comment 20: (S3.A.5. and S4.C.) These two provisions deal with turbidity in surface water discharges. S3.A.5. allows a reduction in monitoring frequency when justified by performance. S4.C.requires a receiving water study when a discharge may be causing a violation of state surface water quality standards. Both provisions are broadly written allowing for subjective interpretation and variable implementation. "I do not have the confidence permit managers across the state will be making like decisions thus applying the GENERAL permit differently among a broad class of significantly similar permittees." The permit should be more precise in defining what criteria will be used to determine if monitoring frequency will be reduced or a receiving water study required. The content of the receiving water study should also be clearly defined. Response: This comment expresses concern about permit language that allows some flexibility in application of the permit conditions and would prefer-precise definition. Ecology agrees with the comment implication that a general permit should provide statewide consistency in the regulation of those facilities covered under the general permit. Ecology also recognizes that absolute definition of all actions taken under the permit will not provide equity for the regulated community or for the environment. S3.A.5.provides for a reduction in turbidity monitoring frequency based on performance. Performance, e.g. turbidity data,must support the conclusion that noncompliance in the future is highly unlikely and therefore reduced monitoring does not present an unacceptable risk to the environment.Itemizing all the factors to be considered and how they would be weighted to form a decision would add significant verbiage to the permit and would still likely fail to cover all the possibilities. As in the concern raised in Comment 10 about"significant process change",Ecology permit managers do share information and develop guidance for consistent implementation of permit provisions. At a recent meeting of permit managers it was agreed that where possible(e.g. normally distributed data), a statistical analysis would provide the primary basis for this determination. S4.C. requires a receiving water study based on the potential of a discharge to violate the state's surface water quality standards. This permit condition is necessary because an assumption was made about available dilution in typical discharges to surface water(see response to comments 13, 14, and 15)that influence permit limits (Special Condition S3.). Since the permit cannot authorize violations of the surface water standards, identifying discharges where problems may exist is not only necessary but in the best interest of the Permittee. Ecology believes the potential to violate standards trigger for requiring a study is sufficiently precise. Like other determinations of this nature, Page'50 FACT SHEET The general permit therefore set a sampling frequency of twice a month. That frequency provides a sufficient number of data points to adequately represent turbidity. The permit does not attempt to define precisely when to take the sample in order to achieve representative sampling. Guidance on proper sampling procedures will be produced and distributed to permittees. It will define the goal of monitoring, how to assess discharge conditions and variability, and application of best professional judgement to arrive at sampling that will assure representative monitoring over time. This approach is consistent with the constraints of a general permit that addresses a group of related facilities and must apply a single set of requirements that are achievable and proportionate to the environmental risk. This approach also puts the burden on the permittee to identify and provide representative sampling for their site. It also has the added benefit of promoting the permittee to visually monitor their site on an ongoing basis and to become familiar with what conditions impact the quality of their discharge water. No change to the permit. Comment 22: (pertaining to frequency of monitoring for turbidity, temperature, and pH.) "It seems prudent to focus monitoring efforts during the time of need rather than through out the year. For example, during the rainy season when soils are saturated and runoff rates are high(e.g. November through March) sampling twice a month for turbidity may be justified, otherwise,we believe that performing this monitoring on a quarterly basis would be more than adequate. Another example is pH. When a source of acidity or alkalinity from an industrial operation has been identified,like the manufacture of concrete or cement,it seems appropriate to monitor pH on a very frequent basis as suggested. In other situations, such as a typical sand and gravel mine,monitoring pH at the proposed frequency seems excessive. Soils in western Washington are generally acid and organic material continually adds to the acidity. Improper interpretation of the monitoring data has the potential to lead to unwarranted notices of violation or monetary penalties for water quality violations." "Lastly,the weekly temperature monitoring requirement appears to be excessive. During the months of July through September, a decrease in rainfall usually results in little or no discharge of storm water for many of these types of facilities so there is nothing to monitor. Those facilities that have a `base flow' situation may warrant temperature monitoring at the suggested frequency during the summer season,but the requirement seems unwarranted for the majority of these types of facilities. It is our position that a better approach would be to require summer quarter temperature monitoring for typical sites which only discharge stormwater during significant storm events and an increased monitoring frequency for those facilities which have continuous or nearly continuous base flow discharging from them." Response: Monitoring frequencies are set to assure compliance with permit limits and conditions. The frequency also takes into account the environmental risk and the ability of the regulated community to execute the monitoring. In a general permit,requirements must also be broad based with little if any variation based on site-specific conditions. Turbidity sampling frequency was largely addressed in the reply to Comment 21. The additional issue raised here is whether frequency should be reduced during the dry season. Besides the added complexity that results from changing requirements by the Page 52 FACT SHEET consideration of a ground water study when the same data has determined other effluents no longer need to be considered based on the data already gathered?" Response: Total dissolved solids (TDS) are a gross measure of the amount of soluble pollutants in the wastewater. TDS can be detrimental to aquatic organisms in fresh water systems and unless significant and immediate dilution is available,it may cause unacceptable degradation. TDS can also contaminate ground water and violate drinking water standards. Data collected under permit requirements of the existing permit included a significant number of values from concrete batch plants with elevated levels of TDS. Elevated levels are those near or above 500 mg/L. There is also evidence that discharges of process water from asphalt batch plant wet scrubbers can have high levels of TDS. Therefore TDS monitoring of discharges of process water from concrete batch and asphalt batch plants is required under the revised permit. A limit on TDS was not set in the permit because there are other factors then just the concentration of TDS that must be considered when evaluating the impact of TDS and potential treatment requirements. The permit purposefully did not define all the study components and requirements so that the study can be adaptive to specific sites, conditions, and data. Equity of implementation across the state will result from a coordinated effort by permit managers. The first year of the permit,will focus only on data collection and evaluation. This will also provide a period of time for Permittees to become familiar with the TDS levels in their discharge. After a year, a representative group of those with highest TDS levels will be selected to further characterize the discharge and consider options. Characterization will look at actual components of the TDS, potential for treatment, AKART, and alternate point of compliance. The results of this group would be used to develop a plan for the remaining facilities that are exceeding 500 mg/L. This process includes Permittee participation and options to resolve any identified environmental concerns. Ecology does not agree that this approach will unfairly limit the Permittee's ability to "evaluate [and apply] practical mitigations". No change to the permit. Comment 25: (S4.D.) "Total dissolved solids are soluble materials found in water. They do not become pollutants unless their character or concentration impact the beneficial uses protected in the State's Water Quality Standards. Brief review of available Eastern Washington ground water quality data, indicates TDS occurs commonly in the 200-300 mg/1 range and,much higher. Hard water,requiring treatment prior to domestic and industrial use,is commonly found. The aquifer system in the Columbia River Basalt Group has increasing head with depth. Artesian water is commonly found bringing high concentration of dissolved solids to the more accessible shallow aquifers and surface water. Response: The ground water standards were adopted to protect the existing and future beneficial uses of ground water [WAC 173-200-030(2)(a)]. At a minimum all ground water should be protected as a potential source of drinking water. Excess dissolved solids are objectionable in drinking water because of possible physiological effects, unpalatable mineral tastes, and higher costs as a result of corrosion or treatment. The state's ground water standards established 500 mg/L as the criterion for total dissolved solids. Page 54 i7 FACT SHEET Response: There are inherent differences between sites with only mining operations and those that have batch plants. A special inactive status for mining locations was included because it is not uncommon at mining sites to operate on a very intermittent basis. Many locations may not be used for years at a time. During this time,equipment and other sources of pollutants are typically removed and with appropriate BMPs in place there is limited potential to harm the environment. Under these conditions an inactive status with no sampling and reporting and minimal oversight was an appropriate balance of environmental risk and permit requirements. Concrete and asphalt batch plants typically do not shut down for long periods of time and inactivity is a result of seasonal fluctuations in product demand. During inactive periods, equipment and materials are more likely to be kept onsite. Under conditions where monitoring is not possible, such as when the site is frozen, "no discharge"is acceptable on monitoring reports. Permittees should consult with their permit manager if other conditions such as impassable roads make monitoring unfeasible. No change to the permit. Comment 28: (S4.F.) This comment also relates to the Fact Sheet discussion of oil & grease and total petroleum hydrocarbons (TPH)on page 12. "Since oil and grease and TPH are so toxic to aquatic life and potentially hazardous to groundwater, I question any de-emphasizing of the monitoring required. Visual monitoring for oil sheen on a self monitoring basis leaves too much latitude to develop laxness or lack of attention." Response: The data may not have been perfect but there was nothing in the data to suggest that continuing to require lab testing would make the picture any clearer. There is agreement that petroleum products are a pollutant of concern and there are many activities in this industry group that could result in petroleum contamination of the environment. The issue is the best way to address that risk and prevent contamination of the environment. The permit requires the permittee to exercise best management practices in any fueling'of vehicles,provide coverage for any storage of petroleum products, and to implement measures to prevent spills,including employee training. In addition,the permit requires prompt cleanup of any spills and daily visual monitoring for oil sheen. Although visual monitoring does not result in a lab analysis for these substances,it places the emphasis on the active process of observing,responding to, and preventing petroleum contamination. We do not believe this is a de-emphasis but rather places emphasis and resources where it can do the most good for the environment. No change to the permit. Comment 29: (S4.H.) There were a number of comments that suggested that the lab accreditation requirements were unfair for some parameters and counter productive. Onsite testing can provide better results than sending samples to a lab for analysis and they provide those results much quicker and at less expense. Allowing more types of basic testing without lab accreditation would result in better permit compliance. Where easy to use meters are available for taking direct readings,they should be allowed and without the certification requirement. Turbidity testing should not require lab accreditation. "Generally somebody that wants to do pH testing, they don't need any type of certification, they just need an electronic meter and presume a certain amount of honesty. If you go and get certified for turbidity,for instance, then the permit says you Page 56 FACT SHEET demonstration project and collect the data. The data could then be presented for consideration during the next permit rewrite in five years. No change to the permit. S6. Reporting and Recordkeeping Requirements Comment 31: (S6.D.) "This provision would seemingly require a permittee to record and submit all field measurements of pH whether done with hand-held meters,in-line meters or meters attached to shutoff valves. Such readings are typically taken as a routine internal means of confirming pH levels. This permit provision would impose an unnecessary administrative burden regarding these routine checks and would be a disincentive for those facilities that take more frequent readings. Field measurements such as these should be excluded from this provision by adding the sentence: `Field measurements of pH including but not limited to litmus paper,portable meters or in-line meters are not subject to this provision."' Response: This permit provision is taken directly from federal requirements (40 CFR 122.410)(4)(ii). However,it is important to remember the intent here. The concern is that if all values are not required, then the Permittee might only choose to do an "official" measurement after unofficially determining they were within compliance. Requiring all monitored values to be recorded also prevents picking and choosing that would statistically alter,the representative nature of the monitoring. The intent,however, is not to require recording of all process control monitoring. In order to distinguish the different events,the Permittee must have clear separation of process control monitoring from monitoring for compliance so that process control monitoring cannot influence timing or frequency of compliance monitoring. If there are questions on how to implement separate monitoring, the Permittee should talk with the permit manager. No change to the permit. S7. Discharge Water Management Comment 32: (SU.) "This provision requires physical coverage of toxic materials is vague and,to the extent some requirement is necessary,this matter should instead be covered in the context of requirements for BMPs or the SWPPP. The list of materials includes several undefined terms such as"toxic materials"or"chemicals,"the latter of which could apply to any substance. The provision also does not specify when coverage and containment must be provided to these substances. For example, does containment apply at all times during the use or storage of these materials? To the extent that other programs that apply.to the handling or storage of hazardous or toxic substances or solid wastes,the requirements of those programs should be referred to in the permit or incorporated. Further, the requirements for containment or coverage should be established for these materials either through BMPs or through the SWPPP based upon the particular materials in question and the risk they present if improperly handled or stored. The blanket requirement for containment and coverage is excessive." Response: This particular provision was also found in the existing general permit as Special Condition S5.E. Eliminating the provision without demonstrating that it is no longer needed would be inappropriate. Covering and containing of toxic materials is still a significant goal for pollution prevention and remains very appropriate for this industry group. There were many examples of sites that had improperly stored and dumped Page 58 FACT SHEET more shallow areas provide a substrate for plants. As a part of a reclamation plan,using the pond as a settling basin may be desirable. Therefore the proposed permit works through the legal dilemma and defines the period of reclamation as part of the mining process. After mining operations cease, solids settling in the mine pit pond is authorized as long as it is part of an approved reclamation plan. No change to the permit. S9. Stormwater Pollution Prevention Plan Comment 34: (S9.B.3.e.) "...there should be some sort of,maybe even an entire section or something in part of your permitting record keeping or in the general conditions having to do with ongoing training of employees and some way of documenting it and that would go along with some method of producing logs that would give an incident report if an employee did find something wrong out there because we all have some feeling that a lot of employers don't like to give their employees training..." "...annual training [is insufficient and] monthly would be more like it. Shorter meetings, not longer meetings. Again, going back to the problem of not enough training. It should be an ongoing thing." Response: There is no disagreement about the importance of training. Ecology certainly would encourage Permittees to establish a training program that will assure that their employees will properly respond to spills and other site conditions as required by the permit.•Guidance in the form a brochure information will also be produced that includes information on the goals and minimum content of employee training. The permit, however, is performance based and annual training is restrictive enough as the minimum level of training required. If employees are failing to respond properly to spills or other problems, it is the Permittee's responsibility to increase training as necessary to achieve compliance. No change to the permit. Appendix C-Definitions Comment 35: "Total dissolved solids, (TDS)is absent from the definition section of the general permit." Comment 36: "Turbidity is absent from the definition section of the general permit." Response: (comments 35 and 36) The definition section was intended to define the significant terms used in the permit and total dissolved solids and turbidity certainly are significant terms. Definitions will be added. Other Permit Comments Comment 37: The Table of Contents does not list all letters that are actually listed in the permit. For example, S 1 in the Table of Contents lists items A-D,however, S 1 in the permit text actually has A-F. Response: S 1. was modified so that all headings would appear in the table of contents. S 11. Stonmwater Inspections, S 12. Spill Plan, and S 14. Compliance with Standards were modified so that headings would appear in the table of contents. Page 60 FACT SHEET sites are noted and an increased effort to identify and permit these sites will be considered. While Ecology can issue fines for discharging without a permit,it is not a legal option to deny a permit solely on the basis of previous operation without a permit. A wastewater discharge permit is issued to regulate discharges to waters of the state and for the most part have not been used as a vehicle to establish prescriptive enforcement measures. There is agreement that enforcement is a part of assuring compliance but enforcement flexibility is preferred over inflexible permit mandates.No change to the permit.
